My environment:
Windows Vista Home Premium Edition Apache 2.2.13 (Win32) MySQL 5.1.38 MySQL Community Server PHP 5.2.10 MediaWiki 1.15.1
I have installed and tested Apache. It's working. I have installed and tested MySQL. It's working. I have installed and tested PHP. It's working.
When I attempt to install MediaWiki, I get an error message telling me that it "Could not find a suitable database driver."
I have only one php.ini file on my system and according to the phpinfo() function, that is the one that is loaded.
Both the php_mysql.dll and php_mysqli.dll are listed in php.ini and not commented out in the extensions section:
extension=php_mysql.dll extension=php_mysqli.dll
Please, can someone suggest something else to check or do that will enable me to install MediaWiki?
